Product Description

Product Introduction
Surge protection device to prevent lightning surge voltage in low-voltage electrical system or solar energy system (photovoltaic power supply system). These devices must be installed in parallel on the low-voltage distribution system or DC power supply system to be protected, and provide common and different modes of protection. Its installation location is recommended to be located at the front end of the household side of the distribution system or at both ends of the DC power line (solar panel side and inverter/converter side), and equipped with matching circuit breakers or fuses.
Product Features
T2, T1+T2 surge protection devices are available for photovoltaic/low-voltage power system.
Module design, easy installation, and replaceable.
The color of the visible window indicates the running status: green indicates normal, red indicates abnormal.
No leakage, no working current.
Remote signal or intelligent monitoring module (optional).

Product Architecture
Product Parameters Overview
Detailed Advantages
Structural Design
New Exterior & Structural Design
A brand new exterior structural design, novel and unique, with good contact performance and large flow capacity. The maximum lightning protection capacity of a single module can reach (8/20us) 80kA, (10/350us) 12.5kA.
Color Recognition
Color Recognition System
A brand new color recognition system with a strip recognition system on the surface of the product, facilitating quick differentiation of various product types.
Quality Traceability
Quality Traceability System
Products achieve visual tracking. Each base is equipped with a QR code recognition system. Scanning with a mobile phone traces factory test data, model, date, and batch, strictly controlling consistency.
Thermal Release
Thermal Release Technology
No external detachment device is required. The detachment device provides reliable interruption, complete isolation after tripping, and self-extinguishing of the arc, avoiding wire drawing.
Plug and Drop
Hot Plug & Drop Design
Replacement can be carried out without interrupting system operation. Pressing the contacts on both sides of the module allows for easy insertion and removal with self-locking functionality.
Arc Insulation
Arc Insulation Board Design
Arc insulation plates installed between each phase and wiring connection prevent arc pulling and flying between phases, ensuring ultimate stability and reliability.
Remote Monitoring
Remote Recording Function
Add remote signaling terminals or intelligent monitoring modules to monitor current and working status, recording and displaying operations via mobile phones or computers.
Installation Options
Multiple Installation Options
Different combination methods can be selected according to varying power distribution systems. Compact design supports four-wire products usable as dual two-wire products.
